Chelsea beware: Why this version of Barcelona are so dangerous

While the core of this Barcelona side has remained constant for a decade now, the club has undergone a revamp under new manager Ernesto Valverde that has brought about incredible results. He hasn't been able to simply continue the work of Luis Enrique, not least because of crucial personnel changes in the squad, and the success he has had so far should not be underestimated. Top of La Liga, in the Copa del Rey final and one of the favourites to win this season's Champions League, another historic treble is still on the cards. This is how they have done it. Life after Neymar Ousmane Dembele was brought in as Neymar's replacement but a serious thigh injury forced an early change of tack. There was nobody else in the squad capable of playing that role, so Valverde switched to a 4-4-2. With one arm gone from the much-feared Messi-Suarez-Neymar trident, the challenge has been creating chances for the two up front when opponents have one less attacker to worry about. Messi and Suarez remain a dangerous duo even without Neymar Credit: Reuters Between them, Lionel Messi and Luis Suarez have 37 league goals this season; the rest of the squad have 22. They have taken on the extra responsibility, and the team has found a new way to get the most of them. They defend deeper and see less of the ball The game plan has shifted: no longer is this the tiki-taka Barcelona of the Pep Guardiola era, nor is it the MSN-led, attack-heavy team of more recent years. Now Barcelona's midfield sits deeper. They cede possession more than before, with Barcelona's average share in league games at its lowest in any of the last 10 seasons, and almost nine per cent down on the peak of 2010/11. Barcelona tactics - Defending deeper Teams are no longer put on “the passing carousel” that Sir Alex Ferguson so memorably referred to, when Xavi, Andres Iniesta and Sergio Busquets were almost impossible to dispossess. They still see a lot of the ball, but there is noticeably less emphasis on pressing frantically to win the ball back as quickly as possible and then keep it as long as necessary to grind opponents down. Barcelona are increasingly comfortable out of possession, too. Messi still does the business There has always been a reliance on Messi (which is fair enough), but it is telling that the number of touches he is having has increased on last season despite a significant drop in the team's overall possession. Barcelona tactics - Messi influence He is playing a more significant role than ever before and when Barcelona get the ball they look to him if at all possible. His touch map from the game against Real Madrid in December shows how much licence he is give to roam, something Chelsea will be desperate to ensure he is not allowed to do tonight. The results are impressive Barcelona are actually facing more shots than in any other recent campaign - 10.58 per match - but the number of shots on target they are facing has not increased, and is just 3.21 per game. Barcelona tactics - Goals scored and conceded Opponents are finding it harder to forge a clear sight of goal against a Barcelona side that are prepared to defend, and they have conceded just 11 goals in 24 league games this season, 15 fewer than Real Madrid. They let in only one goal in six Champions League group stage games, including two clean sheets against Juventus. Although the loss of Neymar has seen a drop in the number of goals they are scoring, it has not meant any less success - a great deal of which is down to that more reliable defence, something they have not always been known for. Barcelona sit seven points clear at the top of La Liga and are adapting excellently to life after Neymar. Chelsea will have their work cut out to stop them.
